Airtac BSE Clamp Standard Cylinder BSE50X600
The AirTAC Airtac BSE Clamp Standard Cylinder BSE50X600 is a genuine double-acting ISO 15552 cylinder with an integrated spring-applied, air-released ROD LOCK. If air is cut or an E-stop is hit, the collet clamps the Ø20mm rod and holds up to 1400 N in either direction — no drift. Ø50mm bore, 600mm stroke, PT1/4 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE50X600
The AirTAC BSE50X600 is a double-acting ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. A collet clamps the Ø20 mm piston rod, delivering a bidirectional static holding force of 1400 N. If air is lost or an E-stop trips, the rod stays locked at whatever position it stopped, preventing suspended loads from drifting.
The lock uses a separate G1/8 release port operating at 0.15-0.7 MPa, while the main cylinder also runs up to a 0.7 MPa ceiling. This SKU lacks a magnet, so position sensing is not available. The lock engages only after the rod stops and requires >=0.5 s to release fully once pressures are balanced.
Rod Lock — 1400 N Static Holding (Ø50mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE50X600 holds its position in both directions when air is lost, exhausted or an E-stop trips. Apply 0.15–0.7 MPa to the G1/8 release port to unlock. Engage the lock only after the rod has stopped (it is not a dynamic brake), and release only when the pressures on both sides of the piston are balanced. Allow at least 0.5 s for full release before moving.

Theoretical Output Force (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa (max) | 1374 N | — |
| Max drive (@0.7 MPa) | 140 kgf | |
Drive force is separate from the 1400 N static holding force of the lock. BSE operates up to 0.7 MPa. Size with a safety margin.

Where the Airtac BSE Clamp Standard Cylinder BSE50X600 Is Used
Vertical Lift Hold
Holds a 1400 N vertical lifting stage in place without live air, preventing uncommanded descent during E-stop or pressure loss.
Tool Clamp Drift Control
Locks a 1400 N suspended machining head securely when air is exhausted, ensuring the tool does not drop unexpectedly.
Pallet Stop Gate
Maintains a fixed pallet stop position during cycle interruptions, relying on the fail-safe collet rather than continuous air pressure.
Is the Airtac BSE Clamp Standard Cylinder BSE50X600 the Right Cylinder?
Verify your suspended load stays under the 1400 N holding limit. If your load is lighter, the BSE40X600 offers 900 N hold and 628 N push at 0.5 MPa. If heavier, step up to the BSE63X600, which provides 2200 N hold and 1559 N push at 0.5 MPa. At 600 mm stroke, use a guide to prevent side loads from damaging the seals and collet. SE mounting accessories fit this body, except FTC. To replace, match the 50 mm bore, 600 mm stroke, PT1/4 port, and no magnet.
Quick checklist
- ✓ Load to hold ≤ 1400 N?
- ✓ Fail-safe hold on air loss / E-stop needed
- ✓ Lock engaged only when stopped
- ✓ G1/8 release-air line available
- ✓ Magnet (-S) for CMSE/DMSE sensors?
Installation & Safety Notes
- check Engage the lock only after the rod has stopped — not as a dynamic brake.
- check Release only when both piston sides are pressure-balanced.
- check Allow ≥0.5 s for full release before commanding motion.
- check Feed the G1/8 release port with 0.15–0.7 MPa clean air.
- check Add safety-rated controls for man-rated / overhead loads.
- check Use SE mounting accessories (FTC excepted).
Airtac BSE Clamp Standard Cylinder BSE50X600 FAQ
The spring-applied collet instantly clamps the rod, providing a 1400 N bidirectional static hold. It is a fail-safe lock, not a dynamic brake, so it must engage only after the rod has stopped.
Drive forces at 0.5 MPa are 982 N push and 825 N pull; at 0.7 MPa, push is 1374 N with a max drive of 140 kgf. The separate static holding force of the lock is 1400 N.
